"Expert judgment improves only when disagreement is allowed to persist.
In a planning call where the timeline is already promised, the room keeps asking for one more datapoint, as if it will remove responsibility. Meanwhile the calendar keeps committing you.
Under pressure, people default to the simplest story. If you do not define the boundary, the simplest story will define it for you. Write it down because otherwise two reasonable engineers will execute two different interpretations, and the system will call it “miscommunication.” Define the decision rights before the crisis, or the crisis will define them for you.
Decide what you will defer on purpose and what signal pulls it back onto the table. That is what makes execution calmer. Make it falsifiable.
